title: Concept analysis of concussion.
abstract: OBJECTIVE
  Concussion has been estimated to occur in 1.6-3.8 million adolescent athletes in the United States each year. However, because of conceptual ambiguity regarding its definition, the true incidence is estimated to be significantly higher. This article seeks to identify and support a single definition for the term concussion.
  
  
  CONCLUSIONS
  Defining attributes, antecedents, and consequences of concussion allow for a better understanding of this concept. Sample cases from pediatric clinical practice further clarify the concept as it applies to pediatric nursing.
  
  
  CONCLUSIONS
  A clear definition has the potential to increase knowledge and recognition of concussion injury, leading to strategies that would decrease the risk of long-term effects and devastating outcomes.
